Description
Technical field
The present invention relates to engine art, particularly a kind of gas machine turbocharger bypass door assembly.
Background technique
Turbosupercharger, because it is to improving engine power, reduce fuel consumption rate, improving effect of discharge aspect, has been widely used in motor.Wherein extensive with the turbosupercharger purposes of exhaust gas by-pass valve, in a large number for diesel engine, petrol engine and gas machine.General turbosupercharger cannot be taken into account low speed and high speed performance, and volute pressurization device low-speed performance less than normal is good, but supercharger impeller easily exceeds the speed limit when high speed, so fall a part of exhaust energy by bypass valve bypass, reduces wheel speed and prevents hypervelocity.Vehicular engine major part all adopts band bypass valve pressurized machine at present.
As depicted in figs. 1 and 2, bypath valve 3 adopts stainless steel to be stamped to form to existing turbocharger bypass door assembly, and rocking arm 2 adopts stamping forming blank to process, and both form by rivet 1 riveted joint again.After riveted joint, bypath valve 3 can rotate freely with respect to the mounting hole of rocking arm 2 together with rivet 1.The applying working condition of diesel engine is generally below rated engine speed, and turbocharger bypass door major part is in closed condition, and now valve does not rotate, and this entirety of valve and rivet is with rocking arm without relative movement, and valve wearing and tearing are few; And the front-seat temperature in diesel engine whirlpool is generally no more than 680 DEG C, so the applying working condition of bypath valve is not severe, on market, the wear-out failure of diesel pressure booster valve is also fewer.
But for gas machine, particularly public transport gas machine, in order to pursue low-speed big and low speed response performance, plateau applicable performance, general institute joins turbosupercharger and is partial to less volute pressurization device, engine speed corresponding when its bypath valve unlatching is lower, and public transport with gas machine frequently start to walk, low speed accelerates, so all frequent switching states in Open-closure of the most of operating mode of turbocharger bypass door.Before gas machine whirlpool, temperature reaches as high as 760 DEG C in addition, so the turbocharger bypass valve of gas machine is badly more many than the working environment of diesel engine.Therefore for gas machine, when bypath valve 3 is opened, under the impact of hot air flow, bypath valve 3 can rotate freely with respect to the mounting hole of rocking arm 2 together with rivet 1, the general opening time of its bypath valve is long, Open-closure switches frequently, the front-seat temperature in whirlpool is higher, and bypath valve wear-out failure is more.
Summary of the invention
The present invention is in order to overcome defect in above-mentioned prior art, provide a kind of simple and reasonable, easy for installation, by the radially degrees of freedom of restriction bypath valve, prevent that bypath valve and rocking arm from relative rotation wearing and tearing, resistant to elevated temperatures gas machine turbocharger bypass door assembly occurring.
For achieving the above object, according to the invention provides a kind of gas machine turbocharger bypass door assembly, comprising: rivet, rocking arm and bypath valve, rocking arm by rivet at bypath valve end face; Bypath valve end face is provided with rocking arm spacing preiection.
In technique scheme, rocking arm spacing preiection is two, is symmetrically distributed in the both sides, end of rocking arm.
In technique scheme, the both sides, end of rocking arm have respectively the semilune boss of an outwardly convex, and the inner side symmetry of rocking arm spacing preiection offers the semilune groove with the adaptive clamping of semilune boss.
In technique scheme, rocking arm spacing preiection is of end sides who is distributed in rocking arm.
In technique scheme, bypath valve is that stainless steel is stamped to form or High Nickel Steel casting forms.
Compared with prior art, the present invention has following beneficial effect: this gas machine turbocharger bypass door assembly is simple and reasonable, easy for installation, by rocking arm spacing preiection being set at bypath valve end face, with the radially degrees of freedom of restriction bypath valve, prevent that bypath valve and rocking arm from relative rotation wearing and tearing occurring, and cause bypath valve to fit badly, stuck, the fault such as come off, the final turbocharger performance that affects, and bypath valve is that stainless steel is stamped to form or High Nickel Steel precision casting forms, high temperature resistant, further improve turbocharger performance.
